Seems unlikely that they would raise prices across the board, it's more likely that they would start some kind of handset leasing program similar to what sprint did with the iPhone, which can generate additional revenue from subprime customers. There is also the possibility of securitizing peoples EIP plans to reduce the amount of money needed to finance peoples handsets.

I believe you can do as many direct rollovers as you want, it's the 60 day rollovers that you can only do once every 12 months. As long as your 401k rollover went directly to your new 401k you should be fine.
